y IMPROVEMENT IN SAD-IRONS. 1

Specification formingV part ofLetters Patent No. 191,908. dated. J une 12, 1877 application filed 'y April 18, 1877.

To all whom it may concern:

Be' it known that I, HARVEY L. WELLS, of

Burlington, in the county of Des Moines and' State of Iowa, have invented certain new and` usei'ul'lmprovements in Sad-Irons; and l do hereby declare that the following isa full. clear, and exact description thereof, which will enable others skilled in the arlJ to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. y

My invention relates to improvements in sad-irons of that class which are provided with a heating apparatus adapted for' being heated by the lighter grades of petroleum; and the invention consists in certain new and improved devices and combinations of devices, all as hereinafter more fully set forth.

In the accompanying drawing, Figure lis a perspective view of a sadiron embodying my invention. Fig. 2 is a longitudinal central vertical sectional View. Fig. 3 is a horizontal sectional view in the line a: :v in Fig. 2.

. Referring to the parts by letters, A represents the sad-iron, having a chamber, A', the

bottomaot' which vis removable, and is secured in place as follows: The forward end of the bottom c is projected up ward and contains a recess, a", which receives the nose or lower front end ot' the upper part, as shown at Fig. 2. The rear end of the bottom has a ange, a'", through which screws b pass and secure it to lugs b on the body of the iron, as shown at Fig. l. The lange a'" has an opening, b", which communicates with the chamber A', and is provided with a sliding cover, b". C is a pipe leading from the chamber A'". D is a vaporizing-plate, and may beconstructed as desired. I prefer a simple plate, with its upper side concave, as shown at Fig. 2. The plate D is placed within the chamber A', some distance above the chamber bottom, and is pierced with a few very small holes, d. The plate D divides the chamber A into an upper compartment, A", and lower lcompartment A'". The walls of the compartment A" are imperforate, except for the admission of a pipe hereinafter referred to, and

the walls of the compartment A'" are partly ot' foraminous material a'", for the admission of air. E is the handle, made hollow, as shown at Fig. 2, .and provided with a cappedV near the center of thel plate D. Immediately exterior to the chamber A" the tube F isprovided with a conical regulating-valve, f, above l which and to its end the tube F is filled with cotton or other suitable material f'.

` The handle E is secured to the iron as follows: Above the wall which forms the top of the chamber A" is a cavity, G, in which is placed .a wooden block, G', to which the handle E is secured by screws h. The block G' only lls a portion oi' the cavity G, the bal-V ance of which is partly filled with burnt alum I, or any other suitable non-conductor of heat, and which will prevent the heat ofthe suhja-v cent iron A from being conducted to the handle The alum I is capped with a retaining-cover, J.

In use the reservoir E is supplied with gasoline or any other light grade of petroleum, which, by capillary attraction, will be carried over through the cotton f', and is dcharged upon the plate D through a small opening or openings in the end of the tube F. To start the heating apparatus a lighted taper or lamptube may-be inserted through the opening b" to heat the plate D from its lower side, heating which will vaporize the gasoline on its l upper side, and the chamber A", becoming filled with said vapor, it will then be forced downward, through the small openings d, into the chamber A'", where it will combine with air entering through theperforated sides a/", and may be ignited and will continue to burn and heat the iron, the smoke, ifany, escaping through the chimney G. A't'ter the vapor ignites, the lamp or taper may be withdrawn, and the heat ot' the burning vapor in the chamber A'" will keep the plate D at a vaporizing temperature of' the duid above it.

The supply of fluid to the plate D may be regulated by the valve f, and it may be entirely cut orf, when desired, by the same means.

r)The sliding cover b may be used to regulate the supply of air to the chamber A necessary to support combustion.

To facilitate heating the bottom a, iron bows k may be secured therein, and extend upward through the ame in the chamber A.

What I claim as new is- 1. The hollow reservoir-handle E, in combination with the pipe F, chamber A', and' plate D, substantially as described, and for the purpose specified.

2. In.combinatio`n with the chambers A A'", diaphragm D, and pipe F, leading from a gasoline-reservoir, an air-regulating valve, b, substantially as described, and for the purpose specied.

In testimony that I claim the foregoing as my own I aiurmy signature in presence of two witnesses.
